Thank you for helping me on solving the question ^^ From the number of posts, you can see that I'm a new user in this forum and I think this is one really awesome forum

so whenever x=e^-3 this equation will not exist? Since denominator will equal to 0 ^^ Im still kind of confused how i should input the interval notation... will it be (0,e^-3)U(e^-3,∞) if I use interval notation? Should 0 be included since ln(0) is undefined

Hi just a quick question Differentiate f and find the domain of f. (Enter the domain in interval notation.) f(x)=(1/(3+lnx)) Here is my Derive: ((-3+lnx)^-2)(1/x) which is correct And for the domain (web assign wants interval notation) When I was doing this part, I wasn't sure if it...

sigh i tried a couple of variations but I ended up being locked up since I reached the maximum amount of trials. Thanks for the confirmation anyway ^^

Hi I'm new in the forum, so if I'm doing anything wrong or made a really silly mistake don't laugh ^^ So we started to learn about differentiating equations not long ago and I'm currently stuck at one question: y = e^αx sin βx My attempt on deriving it...
